[SAJ]

The pepper you're referring to is typically called Thai Red or Thai Dragon. Here's a handy chart of Scoville units for a number of popoular peppers (note: 1 Scoville unit = 1/15th ppm of capsaicin or equivalent):

Pure Capsaicin (USP) -- 15,000,000
Habanero -- 100,000-300,000
Scotch Bonnet -- 100,000-250,000
Jamaican -- 100,000-200,000
Thai Red -- 50,000-100,000
Cayenne -- 30,000-50,000
Serrano -- 10,000-23,000
Hungarian Wax -- 5,000-10,000
Jalapeno -- 2500-5,000
Rocotillo -- 1500-2500
Poblano -- 1000-1500
New Mexico -- 500-1,000
Pepperoncini -- 100-500
Bell Pepper -- 0
Sweet Italian -- 0

Always remember that neither capsaicin (the 'heat' principle in an average pepper such as jalapeno) and oleoresin capsicum (the 'heat' in habanero and Scotch bonnets, among others) are soluble in either water or alcohol. In plain English, water, beer, and wine to cool out a 'burnt' tongue or throat. However, these chemicals are soluble in fat. Pure cream, sour cream, or buttermilk work marvels, and ice cream and sweetened yogurt are also very good for fast relief. In a pinch, smear mashed avocado on your tongue (weird, I know, but it does work).

Hey thanks! The chart says the upper range for the Tai Reds is 100,000 and the lower range for habaneros is 100,000. Now I don't feel like such a wuss.

I dried and ground some habaneros, in the kitchen, I didn't
touch them had rubber gloves on. burnt my eyelids and face,
major heat.
2nd time put a plastic bag over the grinder, same thing, got
burnt even tho i let the powder sit before bottling.
3rd time put the plastic bag over my head, worked ok, except
they need to be bottled outdoors preferably not down wind.
my cousin calls them peppers from hell.

An ice cube on the tongue puts out the fire, too.

The top 3 peppers on SAJ's list are varieties of habanero. They are THE hottest peppers on Earth. In fact, the RED SAVINA HABANERO is THE hottest of the hot, as it hits 500,000 on the Scoville scale.

Food Network had a show a couple of years ago about the hottest peppers, and the Savina was featured. Of course, one lunatic was shown eating one, raw. He was a confirmed "chili-head" who had eaten them many times over the years. He broke out in an instant, pouring sweat, and his eyes teared.
